Here's my iphone carrier pouch I made on the inside of my ab plate. Eric has one too, but his bottom slip came out, we need to replace it.
I'm using the iphone to take pictures, so i put a placeholder in there to show how it goes in.
And for not canon events all my other stuff (Money, Keys, Credit Card, Drivers License) I put in this bad boy (not really applicable for TK) It goes on my belt right before my ammo packs. Nice thing about it is it snaps shut.
